1313K Bearing Product Overview & Core Advantages
The 1313K metric bearing is a double row angular contact ball bearing designed for exceptional performance in demanding applications. Its primary advantage lies in its ability to simultaneously handle significant radial loads and moderate axial loads from both directions, providing a compact and robust solution. Manufactured with precision tolerances and featuring a tapered bore (1:12), it ensures high running accuracy and reliable operation, making it ideal for high-rigidity mounting arrangements.
1313K Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1313 | Standard bearing series designation, indicating the core dimensions (65mm bore, 140mm OD, 33mm width). |
| K | Denotes a tapered bore with a 1:12 ratio, designed for precise interference fits on adapter sleeves or withdrawal sleeves. |
Note: This is an "Open" (unsealed) bearing, as indicated in the specifications. The "K" suffix is the primary designator for the tapered bore feature.
1313K Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides superior stiffness and enables the bearing to support substantial combined loads (radial and bidirectional axial).
- Precision Tapered Bore: The 1:12 taper allows for precise axial displacement during mounting, enabling optimal internal clearance adjustment and a secure, rigid fit on the shaft.
- Optimized Cage Design: The Nylon cage contributes to smooth operation, lower friction, and is suitable for the specified limiting speed of 6,000 rpm.
- Superior Material: Components made from Chrome Steel offer high wear resistance and durability, supporting the high dynamic and static load ratings.
- Standard Internal Clearance: The CN grade radial internal clearance is suitable for a wide range of common operating conditions.
1313K Bearing Typical Application Areas
This double row angular contact ball bearing is engineered for high-performance machinery requiring robust support and precision. Key applications include:
- Pillow Block Housings & Adapter Sleeve Mounts
- Industrial Gearboxes and Power Transmission Systems
- Material Handling Conveyors
- Agricultural Machinery
- Vibrating Screens and other equipment requiring a secure tapered bore fit.
